If you want to visit a web site then you are going through multiple middlemen (gatekeepers): domain name server, server hosting and usually web hosting service providers.
This creates several problems because gatekeepers are vulnerable to hacks and it makes censorship and surveillance easier. It also gives some people unlimited control over the hosting services that can be easily abused.
The internet is controlled by the governments.
The idea is to create a decentralized, people to people web that removes central points – the web hosting services where the information is owned, operated and shared by its users.
The security of the network is provided by public-key cryptography, to make sure that the site cannot be modified without permission.
That would empower the users to host sites they want to preserve.
On this kind of network, the sites get downloaded directly from other visitors. This means, if you have a site with 100 visitors, then it’s hosted by 100 computers around the world. It would be complicated to do something illegal in this kind of network because nodes don’t want to endanger themselves by hosting illegal sites.
